proved construction is applied. Fig. 2 is a plan. Fig. 3 is a sideelevation of the beam and lever-sockets as adjusted for use as a simplebeam, when nothing but an ordinary old-fashioned purchase is required.Fig. 4 shows a side elevation of the improved Amazeen beam when foldedup and not in use. Fig. 5 is a perspective view of the lever-socket 1)with the leverf shipped in. Fig. 6 is a perspective view of one of thefulcrum-links.

Fig. 7 is a perspective view of one of the im-. proved steps e.

Like letters refer to like parts in all the figures.

The center beam on is pivoted iu the middle as usual, but instead of alever of one piece provided with pivotal holes in the same piece, alever-socket piece, I), is furnished with the proper series of pivotalholes and a socket into which independent levers of varyin g lengths mayall be fitted. The lever proper f may then be shipped or withdrawn atpleasure without interfering at all with the pivotal adjustment of thepurchase. The levers are often required to be withdrawn hastily to clearthe deck for other purposes, and when the pivotal pins are withdrawn forthis purpose much care has to be exercised to replace them in the properholes to give the required purchase, while with the socket-piece bfittedwith all the necessary pivotal holes, the levers may be instantlywithdrawn and as quickly re-shipped without interfering with ordisturbing the pivotal adjustment, so that no delay for care in thereadjustment is required, the pivotal adjustment all the while remainingthe same. The usual fulcrum-link c connects the lever- .socket b to thestep with the usual pivotal pins. But the step d is furnished with aseries of holes for the pivotal pin, corresponding to the similar seriesin the lever-socket, whereby, when I place the upper end of link 0nearer the pivotal end of the lever-socket, I am not subjected to thedisadvantage of working the link 0 in an inclined position, but can alsoadjust its lower end in a similar relative position to the lever-socket,and preserve the upright position of its center of oscillation withoutnecessity of changing the pivotal pin in beam to. I can also fold thelever sockets, as shown in Fig. 4, (a very compact and convenientposition when not in use,) without remov ingtheendpivotalpin.Thebeamaistobeconnected in the usual manner by shackles to the primarylevers or pawl-cases of the windlass-barrcl, for which purpose the holes(1 are provided.

The parts may be constructed of the usual materials-cast or wrought, asmay be required.
